Abstract：The acoustic Al electrolytic capacitor used at the circuit with the high fidelity acoustic facility must have some characteristics such as high resonant frequency, little leakage current, no external radia tion magnetic field, no alternating confection and little nonlinear. To make the acoustic Al electrolytic capacitor with little nonlinear and not produce alternating confection, the transient response of the acoustic Al electrolytic capacitor must be good. The investigation show that the factors affecting the transient response mainly involve the original designation, the material and the constructing size of the capacitor, such as the inductance of the capacitor, the characteristic of the oxide film, the movement speed of the ion of the electrolyte, the figure of the cross section of the corrosive Al foil, the electric metal and the mechanical vi beration.
